Help Needed
To all our volunteers and friends

We will need some help on Friday the 11th of August at 09:30 am to check and erect some of our marquees ready for the Open Day.
Also on Saturday our Open Day, the 12th of August at 07:00 am we will need further help to erect the rest of our equipment, tables, chairs, signs etc.
Refreshments will be provided for volunteers. Toilets on site.
All events on the day are FREE. Parking nearby FREE. Refreshments available.
Sunday 13th
A really BIG THANK YOU to all those volunteers and organisers who came along on Friday and Saturday morning to help erect our tents and marquees. Without these volunteers we would not have had the success we had. The weather and the hundreds of visitors made the day really special.

At the Ponds
Damsel flies were dancing across the water and there was lots of action below the water line. We dipped a few creatures out for inspection - unfortunately some of them ate some of the others before we had managed any ID!
There were plenty of efts [immature newts] of varying sizes:

Moth Night!
We should be running a moth trap around the cabin area tomorrow night. Start time will be around 8.30pm, but it won't be dark until maybe 22.30.
All are welcome but from previous experience - we don't tend to catch anything until 30mins after it goes dark. So I expect the first moths to start to be captured around 23.00.
You could have a nice evening stroll around the reserve & come over to the Cabin towards 10.00pm for the trapping, get a nice cup on Tea & wait for the Action!
Meet at Cabin after 8.30pm for Kick off around 10-10.30pm.
Sunday Morning - All the captured Moths should be available for inspection Sunday Morning, where they will be photographed & released around 12-12.30pm.
Hope to see you there!

DAWN CHORUS WALK Saturday May 6th 2017
We continued past Tag ponds spotting common whitethroat,robin and willow warblers singing, perched on top of bushes. We listened to the delightful song of a wren. “A bird that punches well above its weight in song “ Shelagh’s pen identifying bird song came in very useful.Down to the feeding station picking up more birds then onto the lagoon. 4-5 reed warblers noisily making their presence felt, defending their territories. A heron flew over and little grebes were calling.By now some children were feeling cold so we made our way back to the cabin. Here Robin and Chris set up camping stoves and very soon the tantalizing smell of cooking bacon was apparent. Bacon butties !! what a splendid way to finish a most enjoyable walk.Many thanks to everyone who took part.
There is another walk next Saturday 13th , May do come along.

Get ready... and click!
Lots of people say how much they enjoy the photos on our blog. It takes some patience and a bit of cunning to get a photo you're pleased with so if you want to have a go at home in your own garden here are a few hints to get you started ...... from a total amateur!
-
Put small amounts of food out regularly – especially on bird tables. This keeps mess to a minimum and is healthier for birds as they are not eating old and mouldy food. Your birds will learn your routine and will be ready and waiting, so it's good to keep a camera or your smartphone handy.
-
Put out food they have to stay and eat, rather than things they can fly away with – larger pieces mean they have to peck bits off while you get your photo. Bread isn't really good for birds, so try fatty scraps, invest in some sunflower seeds or fat balls and meal worms [dead ones in packets are not unpleasant to deal with].
-
Wedge things like peanuts, fat or cheese rind into cracks in a stump or branch so they'll have to work a bit to get at them. Drill a few holes if necessary!
-
Get to know where the birds like to perch – some prefer to pause on a nearby branch or fence post to check things out before they approach. So set one up or trim back a few twigs if they are in your way.
- give them some water too - a large plant tray will make a great bath for a flock of sparrows.
Whether you photograph them or not your garden will be a great place for birds - enjoy!

Chiffchaff Nature Reserve
On a walk around the reserve today produced
27 species and Green Woodpecker and Treecreeper
heard but not seen, loads of Chiffchaff all over the
reserve and the Little Grebes making a racket on
the lagoon, I only seen one but it sounded like there
were a few more on there, and 2 Goosanders were
sunbathing up by the weir.
